I prefer the non-M Sport. The way the M Sport's painted part of the bumper integrates into the side intake and fog lights is very awkward. I think the non-M Sport looks surprisingly nice, and much better than the concept.

Looks like you are right.The circular camera in the lower part of the bumper and the the lighter white color in the M50d pic make it look quite different.The X7 with the M Sport bumper i saw at the event last week was carbon black and the bumper looked very clean.I guess it will be busier looking in a lighter color.
